Add filesystem events to the timeline

[szegedi]

What does this PR do?

Adds filesystem events to the timeline.

Motivation

Users can have even more information in the timeline. Additionally, filesystem operations use the same worker thread pool that DNS operations use, so we have a better insight into its use (for reporting of oversubscription.)

Additional Notes

This is implemented by listening to our apm:fs:operation:* diagnostic channels. I took care to not gather information for *Sync calls as they show up as blocked stack traces in the main thread anyway. Additionally, we are selective about what parameters of methods we gather (not gathering strings when they can be data.)
